. My invention relates to railway rolling stock and consists in an improved mounting ofboostermotorsinlocomotives.

My invention is a licable to that of locomotive havin a ailer'axle and w eels and including a r motor operatively connected thereto and partially supported thereby.

The main main frame of the locomotive, thereb eliminating the necessity of a trailer truc or, 1f web a truck is used, relieving the trailer truck frame of the. weight of the booster m0- tor and making it possible to lighten the trailer truck frame. n I

Particular objects of my invention are to provide pivotal means for suspending the motor from the locomotive frame, to provlde a universal joint support for the end of the booster motor spaced from the trailer axle, and where a trailer truck is used, to connect the booster motor with the truck frame at a point spaced from the axle so as to swing the motor with thetruckframe and axle irrespective of the supgiort from the locomotive frame. I desire at the motor be rigidly supported from end to end irrespective of the variations in the relative position of its supporting elements and irrespective of any movement of the motor transversely of the locomotive frame.

This application is in rt a continuation of my copending a hcation Serial No. 559,658 filed May 9, 1 .v In e drawings illustrating my invention- Figure 1 is a top view of the rear end of a.

locomotive frame rovided with a trailer axle and wheels and a r motor which is carrf ied by the trailer axle and by the locomotive Figure 2 is in art a side elevation and'in part a vertical on 'tudinal section of theequipment illustra in Figure 1.

object of my invention is to partially support the booster motor from the.

PATENT orslcs.

Figure 4. is a vertical longitudinal section through the structure shown in Figure 4.

F'gure 4" is a top view of the structure shown in Figure 4. a

Figure. 5 1s a rear elevation of a locomotive frame and booster motor and illustrates another modification of my invention.

The rear rtion or cradle of the main frame of the ocomotive is indicated at. 1' and it will be understood that the forward I rtion of this frame constitutes no part 0 the a present invention and that this forward rtion is mounted upon the main trucks 0 the locomotive in the usual manner. his frame is at 2 to receive the journal boxes of a trailer axle 3 mounted by wheels 4. The main frame 1 is partially supported :5 the trailer axle through sp 1 suppo u on the trailer axle joufiboxes and exten rearwardly beyond the same to a point substantially spaced from the trailer axle 3.

A booster motor including a frame 5 is provided with spaced bearings 6 and 7' upon trailer axle 3, which bearingspermit the motor frame to swing, in a vertical plane, relative to the trailer axle and cause the booster motor to swing with the axle in a horizontal I plane. y

The rear of the locomotive frame is provided with hangers 8 from which links 9 are: pivotally SllSPBlldGd/Lt opposite sides of the rame of the locomotive and of the motor frame. The lower ends of links 9 suspend a cross bar 10 which is provided with a universal joint bearing for the booster motor frame comprising concave-convex plates 10' and 10". A bolt10 through beam 10 plates 10 and 10", and motor frame 5 and yieldingly holds these parts in the position shown alth0ugh the provision of sp 10 and the enlarged bore through lates 10' and lOand framefiaxis of axle 3 and the longitudinal axis of the locomotive frame.

In Figures 4, 4} and 4 the locomotive main frame is indicated at 15 and includes brackets 16 which support the rear end of the main frame upon a trailer truck frame A having a rear cross member 11. The booster motor 18 is suspended from the main frame by links 19 which pivotally support cross-bar 20 provided with a convex bearing element 20" fitting a corresponding element 20 in the motor frame.

In order to take the strain of the shifting movement of the booster motor from the bearings onthe trailer axle, I connect the rear cross member 11 of the trader truck with the booster motor frame by means of a horizontal link 14 pivoted at opposite ends to motor supportingbar20, and to the trailer truck frame, respectively, and serving to push or null the booster motor frame transversely of t e locomotive frame according to the relative movement of the trailer truck frame.

My preferred construction contemplates the use of a cast steel locomotive frame, a cast steel trailer truck frame, and a cast steel booster motor frame, thereby insuring maximum rigidity of these frames and the most efficientdistribution of the metal for the work to be done.

The construction described removes the weight of the booster engine entirely from the trailer truck frame, distributing it to the trailer axle and the locomotive frame. This enables the use of a much lighter trailer truck frame than would be otherwiserequired.

Various other arrangements of the boostermotor mounting mag be provided, Without departing. from the road idea embodied in the above described constructions, and in Figure 5 I illustrate a modified structure adapted to be used in that type of locomotive having a rigid or non-radial trailer axle in which it is only necessary to provide for movement of the booster motor to accommodate relative vertical movement of the trailer axle and the locomotive frame or movementof the opposite ends of the trailer axle relative to the locomotive frame which tends to produce twisting of the booster motor, either in horiappear to those experienced in the art and I contemplate all such as fall within the scope of the following claims.
